To all whom it may concern:

' Be it known that 1, WILLIAM KEMP, a citizen of the United States, and a resident of Tucson, in the county ofPima and Territory .ofsArizona, have invented new and useful Improvements in Burners for Hydrocarbon Vapors or the Like, of which the following is a 'full, clear, and exact description. Myinvention relates toburners,andadmits of general use, but is peculiarly applicable to burners of a type for use in connection with w h drocarbon vapors or the like, and is prefer- .a 1y. employed 1n connection with furnaces for smelting ores. Reference is to be had to the accompanymg drawings, forming a part of this specificatron, in which similar characters of reference ndicate corresponding parts in both the figures. Figure 1 is a view in vertical section, show- 111g my invention as applied toa furnace for smelting ores; and Fig. 2 is an enlarged vertical sectional view showing the position of the burner mechanism proper. 1

.The furnace is shown at 1 and is lined at its bottom with brick'2, being provided with an inner wall 3, the top of WhlG is somewhat thinner than its bottom. The water-jacket 4, filled with water 5, is surmounted by anotherwater-j acket 6, filled with Water 7." The burner-casing is shown at 8 and is provided with flanges 8, secured in position b means of bolts 8 A brace-rod 9 is provi ed with bolts 1 11 for the purpose of securel holding cured in position by means-of a. bolt 13. A similar foot 14 is provided with a bolt 15 and serves to secure the Water-jacket 6 firml' in position upon the water-tight jacket 4. 'The up er portion of the burner-casing 8 is provi ed with ,the casingis closed by ahead 18, provided with a peep-hole 19, and over this peep-hole is a drop-door 20. In the necks 16 17 are a mounted the air-supply pipes21 22, rovided, res ectively, with gates 23 24. ounted wit the burner-casing- 8 is a cylindrical body or baffle-cup 25, a number of annular channels 27 28 bein formed in the body. by means of the severa cylindricalmembers or walls 3061 32, and an'annular inwardly-projecting bead 33 is formed or mounted'upon theb nor-casing in position. The owerend" of the'brace-rod rests against a foot 12, se-

necks 16 17, and the outer end of the cylindrical head of the body 25. A tube 34 passes through an o ening therefor in'the head of the body or ba e-cu and is con- .nected with a cylinder 35. This cylinder is provided at its outer end with a ring 36 of the sha e in cross-section Shown in Fig. 2, and against this ringbears a acking 37, secured in-position a stufling-box. A tube 39, mounted in the head 18, is provided for a suitable distance from its outer end with threads 40 and is also provided with a duct at 41 and with a flaring portion 42 at its inner end or extremity, the outer face of which is parallel with the beveled edge 43 of the tube 34, the inner portion of said tube 39 passing through said tube 34, as shown, and said flaring portion 42 constituting'a valve for either regulating or cutting ofi the vapor mixture passing toward the furnace from between the tubes 39 and 34 by roperly manipulating the adjustin device hereinafter referred to. A threaded cap 44 closes the upper end of the tube 39, and working in this cap is a threaded portion of a stem 45, revoluble by means of a hand-wheel 46, mounted on the outer end of said stem. Up on the inner end of the stem 45 is mounted a conical valve 47, and by turning the hand- .wheel 46 the valve 47 may be moved into and out of proximit to the flared surface 42of the tube 39, which serves asa valve-seat. clamp 48, provided with a threaded member 49 for en aging the threads 40 on the tube 39, is secure upon a tubular member 51, passing through an opening therefor'in head 18 an connected at its inner end with a neck 50, supporting and being in communication with the cylinder 35. Mounted within the tubular member 51 is an innertubular member 52 of smaller diameter, provided with longitudinal slots 53, these slots being'disposedradiall into the tube 39 prevents the destruction of the tube and other parts ofthe burner, and this same action assists in heating the air passing through the tube 39 to unite with the vapor mixture passing from the s ace; between said tube and tube 34 into th drical hollow body or baffle-cup 25.

A threaded sleeve 54 is secured outer end of the tubular member-51, anda ri 55 encircles the sleeve 5'4, and mounted wit this ring is another ring 56, which is by a cap 38, t ereby constituting The duct 41 by permitting air to flow free y e cylinuponthe through the tube 39, going outward threaded for the purpose of making a secure engagement with the ring 55. A sleeve 57 is mounted upon the outer end of the inner tube 52, and between the sleeves 56 and 57 is another sleeve 58, closed bya cap 59,connected with a steam-pipe 60. By means of a' neck 61 the sleeve 58 is in communication with a pipe 62, which serves to supply hydrocarbon vapor to the interior of said sleeve 58, thence to the tube 52. A nozzle 63, having a general talpering form, is connected with the cap virtually constitutes the terminus of the steam-pi e 60, said nozzle extending Within the tu e 52 for a suitable distance from the outer end of the latter. The other end of the inner tube 52 is closed by-a screwplulgl64.

e water-jacket 4 is rovided with an a e'rture 65, the walls of w 'ch are disposed obliquely, as shown in Fig. 1. An air-jacket 66 of flaring form is dis osed partially within the burner-casin 8 an partlally within the aperture in t ewater-jacket. This air-jacket is rovided with holes 67 and forms an annu ar aperture 68, through which the air divides and passes. The object of the air-j acket is to protect the metal-work against the heat of the flame, and the air thus used in absorbing heat is used for oxidizing sulfur and the like in the treatment of cotton matte.

My invention is used as follows: When the air is turned on through the ipes 21 22, the draft being regulated at will y means of the gates 23 24, steam passes through the pipe 60 and the nozzle 63 to the inner tu ular member 52 and in its escape from the nozzle produces an aspirating effect, thereby raising the hy drocarbon liquid through the tube 62 and causing hydrocarbon vapor to pass radially outward through the slots 53, thence throug the neck 50 to the cylinder 35, thence between the tubes 34 and 39 and through the an nular bead 33 to the inner cylinder or member 32. The air from the pipe 21 passesinto the casing 8, and the reater bulk of this air then passes through the annular channel 27 to the free end of c lindrical' member 31, thence back to the f ree end of cylindrical member 32, (through channel 28,) and finally out through space 29 between wall 32 and bead 33. A ortion of the air passes upwardly throug the duct 41 and to the left past the flange-42 and the valve 47. This air is admixed with vapor passing outwardly from between the tubes 39 and 34, the admixture taking lace within the bead 33 and being driven to t e left through the inner cylindrical memher or wall 32 directly to the furnace. The combustion takes place within the bead 33 and the inner cylindrical member 32. The portion of air passing into the channel or assa e 27 es to an annular bottom 27 of t 1e bo y or affle-cup 25 and is there baffled thereby, returning to a point immediately ad acent to admixed with the hydrocarbon vapor and steam, the cylindrical members 30 and 32 thus serving as a baffle-cup, the cylindrical member 3 1 being a dividing-partition for causing the air to pursue a sinuous path from one end of the cup to the other, then back toa point near the bead 33. The air following this sinuous ath is heated before being admixed with t e hydrocarbon vapor and with the ases of combustion as the are produced. Air from the ipe 22 asses downwardly and around the cylindrica or annular member 30, being therebyheated, and this air then passes directly to the flame. By absorbing heat it accomplishesa twofold object-to wit, it promotes better combustion and also tends to revent the baffle-cup from bein unduly heated. This air in passing throug the airjacket 66 is redistributed in a sense and is divided, a portion passing directly into the furnace and another portion passing toward the axis of the burner and in the general direc tion of the furnace. The air thus passing throu the jacket, and thereby becoming heated, serves to protect the metal-work from undue heating and also enters the flame at a higher temperature than would otherwise be the case.

The outer tubular member 51, the inner tubular member 52, provided with the slots 53 and the nozzle 63 constitute a mixing-tube, as above described.

I find that the results obtained by this furnace are greatl improved in consequence of the baffle-cup ormed of the inner and outer cylindrical members 30 32 and the cylindrical web 31 for guiding the air through the same. By properly manipulating the nut 49 in clamp 48 it is apparent that tube 39 may,

be adjusted to operate the flaring portion or valve 42 at the inner end of said tube.

It will be understood that the lower ends of the cylinders 32 and 30 may be practically integral with the so-called annular bottom 27 therebetween, while the upper ends thereof are open, as shown. T e intermediate cylinder 31 is separate from the others of course, and its upper end may be practically rigid with the part (head) designated at 25, having the tube. 34 extending therethrough and into the inwardly-projecting bead 33. In this way the tubular structure referred to may be supported relatively to the members 006 erating therewith.

' aving thus described my invention, I claim as new and desire to secure by Letters Patent In a burner for hydrocarbon vapor and the like, the combination of a casing, a baffle-cup within the casing, comprising inner and outer c linders having a s ace between the two clbsed at one end an 0 en at the other, together with'an interme iate cylinder, closed at the end thereof adjacent to the open end of said space and open at the closed end of the space; means for delivering hydrocarbon vapor to said inner cylinder, and means for su plying air to and through said baflie-cup, t' e closed end of said intermediate cylinder having an annular bead extending Within the open end of said inner cylinder.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

WILLIAM KEMP.
